State Route 160/Highway 4 Direct Connector Ramps

State Route 4 construction.

The existing State Route 160/Highway 4 interchange currently includes only two of the four possible interchange movements: the eastbound Highway 4 to northbound State Route 160 connector ramp, and the southbound State Route 160 to westbound Highway 4 connector ramp. The State Route 160/Highway 4 Direct Connector Ramps project will construct two new connector ramps, one connecting westbound Highway 4 to northbound State Route 160, and one connecting southbound State Route 160 to eastbound Highway 4.

The project scope includes adding an additional 12-foot auxiliary lane to the outside of existing State Route 160 in both directions between the State Route 160/Highway 4 Interchange and the East 18th/Main Street Interchange, as well as building a soundwall extension and retaining walls. The southbound State Route 160/Highway 4 separation structure will accommodate a future BART extension in the median of Highway 4.
